WATER-CLOSET VALVE.

QPECIFICATION forming part of Letters Patent No. 299,888, dated June 3,1884:.

Application filed June 19, 1883. (No model.

To all whom it may concern:

Be it known that 1, PETER WHITE, of St. Louis, Missouri, have made a newand useful Improvement in \Vater-Closet Valves, of which the followingisafull, clear, and exact description, reference being had to theannexed drawings, making part of this specification, in which- Figure 1is a-plan of the improved valve; Fig. 2, avertical longitudinal section,the main and the relief valve being closed; Fig. 3, a similar section,the valves being unseated; Fig. 4, a section on the line 4: 4 of Fig. 3;Fig. 5, a section on the line 5 5 of Fig. 4.; Fig. 6, a section on theline 6 6 of Fig. 2, and Fig. 7 a

. section on the line 7 7 of Fig. 2.

The sameletters of reference denote the same parts.

A represents an ordinary float, such as used in water-closets. It isattached to the lever B, which is made open at b in the usual manner toreceive the handle of the ordinary discharge-valve, which, as itsconstruction is well understood, is not here shown. The lever isprovided with an arm, b, which at 7) is pivoted to the stem 0 of therelief-valve O, and is extended at b to pass and work between the lugs dd, that are upon an extension, (1', of the cap D, which incloses therelief-valve G. This valve 0 seats outwardly against the seat 0, whichis a rubber washer held between the cap D and that part c of themainvalve-chamber E, which forms the relief-valve chamber. The stem 0- worksthrough the cap D, and such water as passes the relief-valve isdischarged at 0 into the closet-basin. (Not shown.)

F represents the mainvalve. It seats at f, and is attached to the stemf, which is extended to work loosely through the valve-chamber E at c,and, on the other side of the valve, is extended to receive and haveattached to it the cup-leather G. The cup-leather works in the chamberH, which at its end h is open to the space in which the main valve Fworks, and at h is grooved. The groove h extends in the wall it of thechamber from the end it through to the other end, If, of the chamber H,or to beyond the limit of the movement in that direction of thecup-leather G. The chamber H at the end h is closed, saving the outleth. Opposite the outlet h is an annular groove, h

The groove It leads into the groove h. The outlet h leads into apassage, h, whichin turn leads into the space in which the relief-valveworks. A spring, I, encircles the stem f 'and bears against the cap J,which incloses the valve-chamber at that end, and aids, by pressingagainst the cup-leather, to seat the main valve when the pressure isweak. The chamber H is preferably-made in one piece with the cap J. Theinlet to the valve is at K, and the water passing the main valve flowsout and is discharged at L.

The action of the valve is as follows: WVhen the contents of thecloset-basin are discharged, the float A drops. This causes, as shown inFig. 8, the relief-valve to unseat, whereupon the water thatis confinedwithin the chamber H beneath the cup-leather is discharged through thepassage h, past the relief-valve, and out through the outlet 0 Thepressure beneath the cup-leather being thus relieved, the main pressurethrough the inlet K acts to open the main valve, and the water thenflows past the main valve into and fills the closet-basin again. Thiselevates the float A again into the position shown in Fig. 2, causingthe relief-valve to seat again. The water-pressure, on the seating ofthe relief-valve, forms again beneath the cup-leather, and the mainvalve thereby becomes balanced substantially. The water flowing past themain valve then acts to suck that valve to its seat, and the flow ofwater into the closet basin ceases. The main valve, however, would notbe sufficient-ly free to enable it to be thus seated were it not for thegroove h. Through this last-named groove asmall amount of waterflowsbeneath the cupleather in the chamber H, and thus prevents a vacuum fromforming beneath the cup leather, and holding the cup-leather and mainvalve from moving toward the seat f.

It is obvious that when the cup-leather G rises to seat the main valvethere would be a vacuum formed in the chamber H, if the groove h werenot provided to allow said chamber to be filled with water, which latteris expelled through side passage, h", when the cupleather and its valvedescend to form a communication between the inlet K and outlet L.

By pivoting the float-lever directly to the reliefvalve stem,the latteris more readily moved. The lugs (Z (Z serve as fulcra for the lever-armI) to bear against. The main valve stem is enlarged at f to fit theopening in the valve-chamber. This serves to prevent the main valve fromclosing too suddenly.

I claim 1. A water-closet valve having inlet and discharge passagesabove the main valve, and an outlet-passage leading from below thisvalve to a chamber, H, below the relief-valve, and

h and the outlet h, with the inlet and discharge passages, and the mainvalve F, substantially as described.

4. In a water-closet valve having inletand discharge passages above themain valve, a chamber with an outlet below this valve, a groove, h, apassage, h, a relief-valve, C, the extension (1, lugs (Z d, cap D, andafloat-lever attached to the stem of the relief-valve, substantially asdescribed.

5. In combination with a valve constructed with a side outlet-passage,7L5, leading from a chamber below the main valve having a groove, h, therelief-valve 0, having a float-lever pivoted to its stem, substantiallyas described.

\Vitness my hand this 5th day of June, 1888.
